Abstract: PURPOSE:To heat a food to be cooked uniformly by providing a hot air blow-out port on the downstream side of the flame forming section of a lower burner and, at the same time, providing a plurality of air flow direction control plates substantially in the center of this blow-out port. CONSTITUTION:The blow-out speed of a mixture gas is extremely high at the blow-out port 23 because the mixture gas is quickly changed into a high temperature gas and its volume is increased much and the distance of its reach is extended enormously. On both sides of the blow-out port 23 an air flow direction control plates 22 are provided, making the flow near both sides of a heating chamber 15 very much upwards, and this makes the temperature distribution in the room extremely non-uniform. When the air flow direction control plates 22 are provided almost uniformly at the whole blow-out port 23, the temperature on the side of the far end of the heating chamber 15 is higher and the temperature near the side walls of the front face is lower. Accordingly by providing a plurality of air flow direction control plates 22 with their distribution being dense only in the central section the flows of the high temperature gas near both side faces of the heating chamber 15 are mainly parallel flows and the upward flows are suppressed to make the temperature distribution in the heating chamber 15 substantially uniform all over up to near the side walls.

Title: Device for releasing power saving function
Inventor: SHIMOBABA KAZUNARI
IPC: G06F1/32
Filed: 1998-10-30
Abstract: PROBLEM TO BE SOLVED: To save electric power, miniaturize a power supply and also stabilize operation by controlling electric power to the state of low power consumption for each circuit via an intermediate power consumption state, by determining the releasing time of the low power consumption state for circuits, and by deciding the interval of the transition time between power consumption states that continue. SOLUTION: In a normal state of waiting for the input of a command, a demand for starting power saving function is outputted to start the transition to power saving state, either when the command waiting state continues for a certain period of time or when a user wants the power saving state. A timer for transferring power saving mode is started to take steps to the power saving state. Then, the power saving states of circuits are judged to determine the order of circuits for which power needs to be saved and the interval of starting the power saving transfer timer. Also, whether or not any circuit for which power needs to be saved still remains is determined. If not, a central operating and processing device that controls this device totally is shifted to the power saving state to finish the power saving process.  As a result, the wasteful consumption of electric power by circuits can be suppressed, the failure of a system can be prevented, and the size of a power supply can be miniaturized.

Filed: 1986-12-25
Abstract: PURPOSE:To obtain a stable operation without a reverse flow of current even if a reverse potential different from the conventional one is applied, by not bringing an well layer into contact with a second high potential source. CONSTITUTION:Assuming that a second high-potential point 2 is higher in its potential than a first high potential point 1, an output 7 is on a level of the second high-potential point when a signal d is on a L level, and the output 7 is on a level of the first high potential point when the signal phi is on a H level. However, when the signal phi is on the H level and the output 7 is on the level of the first high-potential point and if the second high-potential point 2 is smaller in its potential than the first high-potential point 1, a current flowing from the high-potential point 1 through a P type diffusion layer 12 and an N well layer 11 is interrupted so as not flow into the second high-potential point because a N<+> diffusion layer has been removed contrary to the conventional technique. Since a well potential of the N well layer 11 is applied through a parasitic diode 17, no hindrance occurs in transistor operations of PMOS 3 and 4.
